Q

Disadvantages of supraglottic airway

A
  • not a definitive airway
  • does not provide protection against aspiration (in fact, with an LMA, it increases risk of aspiration as stomach contents would most be directed into trachea)
  • during prolonged ventilation, some wire may be insufflated into stomach because seal made at airway isn’t airtight
